Do I have to pay state taxes when I did not even go to said state during 2020? How did I earn wages there without going to this state at all

Usually you need to file state return for the state that you live or work in.

If you employer withheld taxes from a state that you didn't live or work in, file a Non-Resident State Return to have them refunded to you. Notify your employer right away so it doesn't happen again!

You also need to prepare a return for your resident state. You will report all of your income, including income from any nonresident.
